Title:
DISPOSABLE JET INJECTOR
Document Type and Number:
WIPO Patent Application WO2001030419
Kind Code:
A3
Abstract:
A jet injector is described which clips to the front of a standard drug ampoule (1) and is energised by pressing the assembly against the skin of the patient. The pressure deforms a biaxially curved spring (13) which buckles reversibly to impact the drug delivery tube (5), causing a high pressure transient. This generates a high speed droplet which cuts a track in the skin. The drug may then be administered with a syringe in the normal manner. An elastomeric non return valve (11) may be incorporated.
